By default each transaction in Siebel CRM application makes a large number of serialized mprotect() calls, which in turn may degrade the performance of Siebel. When the load is very high on Siebel enterprise servers, the mprotect() calls are serialized by the operating system kernel resulting in high number of context switches and low CPU utilization.

If the application exhibits these pathological conditions, performance thus scalability of the application can be improved by reducing the number of mprotect() during run-time with the help of AOM tunable MemProtection=FALSE.

From the command line version of Siebel Server Manager, run:change param MemProtection=False for comp <component_alias_name> server <siebel_server_name>

where:component_alias_name is the alias name of the AOM component to be configured, such as SCCObjMgr_enu for the Call Center Object Manager; and

siebel_server_name is the name of the Siebel Server for which the component being configured.

The MemProtection parameter is hidden; and the value of this parameter is TRUE by default.

For more information about this tunable on Solaris platform, check Siebel Performance Tuning Guide Version 7.7 or 8.0 in Siebel Bookshelf.

Recently I've been reading Dilbert comic strips from mid 90s; and I couldn't help but notice some striking similarities in the way both Jon Arbuckle (Garfield's owner) and Dilbert (Dogbert's owner) crave to get a date or how they ruin their date, when they have one. There are similarities in the sarcastic comments made by Garfield and Dogbert too, toward their owners Jon and Dilbert respectively.

Dilbert Vs Seinfeld

Unlike Dilbert, Seinfeld is too smart to get as many dates as he like; but it appears both Dilbert and Seinfeld follow the same etiquette when they run into the same person more than once in the same day. For instance, in one of the Dilbert strips titled Hallway Etiquette, Scott suggests the following simple three rules, with Dilbert as one of the characters in the comic strip:

First hallway meeting of the day: Greet Good Morning / Afternoon / Evening.

Second hallway meeting of the day: Raise your eye-brows and give a tight-lipped smile.

Third hallway meeting of the day (and there after): Sneeze to avoid eye contact, try to hide etc.,

I don't remember the exact Seinfeld episode (there are just too many), but in one of those 176 episodes, Jerry Seinfeld makes similar suggestions to his audience in the opening monologue or to his friends, George Costanza, Elaine Benes and Cosmo Kramer, in the play.

In another Dilbert comic strip, Dilbert and his co-worker asks a lady "When's the baby due?". "Can't a woman go off her diet for one day without getting that question??" replies the irked lady, just like the character Maryedith responds to Kramer's "Are you sure you're not pregnant?" in The Parking Space episode of Seinfeld.

It's been exactly one year since I had my last post of this series, My Favorite Music VI. I guess it is the time for few more favorite songs. Click on the links to open up the videos in YouTube video player.
